AI-Powered Cyber Threat Intelligence (CTI) Platform

Overview

A production-grade Cyber Threat Intelligence (CTI) platform designed for automated ingestion, enrichment, correlation, and analysis of security threats from real-world sources.

This system functions as a lightweight Threat Intelligence Platform (TIP), conceptually aligned with systems such as MISP and commercial CTI solutions. It is designed for operational cybersecurity use, not as a demo or academic prototype.

All generated output, logs, reports, and documentation in this repository are maintained in English only.

Current implementation status: Phase 2: Intelligence Enrichment Layer Implemented.

Core Capabilities

  • Real-time threat intelligence ingestion from verified security sources
  • Structured CVE-based vulnerability analysis with CVSS scoring
  • IOC (Indicators of Compromise) extraction and correlation (IPs, domains, hashes, URLs, payloads)
  • AI-powered threat analysis (DeepSeek API with fallback mock mode)
  • Threat scoring engine (0–100 risk model with weighted signals)
  • MITRE ATT&CK mapping for attacker behavior classification
  • Historical context storage using SQLite
  • Deduplication and stateful processing (SQLite)
  • Multi-format reporting (JSON, Markdown, CSV, CTI-ready exports)
  • Optional alerting system (Telegram, Discord, Slack integration)
  • Enrichment layer (NVD, CISA KEV, MITRE)
  • Campaign correlation engine (shared CVE/IOC/software grouping)

Supported Intelligence Standards

This platform aligns with industry CTI standards:

  • MITRE ATT&CK Framework — Attacker tactics and techniques mapping
  • CVE / NVD — Vulnerability identification and CVSS scoring
  • CISA KEV — Known Exploited Vulnerabilities database
  • STIX-like format — Structured threat intelligence exchange (internal)
  • IOC standards — IP, domain, hash, URL, malware indicators
  • Common Weakness Enumeration (CWE) — Weakness classification

Threat Scoring Model (0–100)

Each threat is scored using weighted intelligence signals:

Signal Weight Impact
CVSS Base Score 30% Primary vulnerability severity
Active Exploitation 25% KEV listing or public PoC available
Malware Association 20% Malware family linkage or campaign
Attack Surface 15% Public-facing assets affected
Ransomware Linkage 10% Known ransomware campaign

Auto-escalation Rules:

  • KEV listed → minimum high severity
  • Active ransomware → automatic critical escalation
  • Public exploit available → score boost (+15 points)
  • Mass exploitation detected → score boost (+10 points)

IOC Extraction Engine

Automatically extracts and normalizes Indicators of Compromise:

IOC Type Examples
IPv4 Addresses 192.168.1.1, 10.0.0.0/8
Domains attacker.com, c2.evil.org
URLs https://malware.site/drop.exe
Email Addresses attacker@domain.com
SHA256 Hashes a1b2c3d4e5f6...
MD5 Hashes 5d41402abc4b...
PowerShell Payloads Base64-encoded scripts
Encoded Payloads Base64 / hex-encoded data
Malware Infrastructure Dropped files, C2 indicators

Output is normalized, deduplicated, and stored for correlation.

MITRE ATT&CK Mapping

Each vulnerability is automatically mapped to:

  • Tactics — e.g., Initial Access, Execution, Impact, Persistence
  • Techniques — e.g., T1190 (Exploit Public-Facing Application)
  • Sub-techniques — Granular attack methods

This enables:

  • Attacker behavior classification
  • Campaign correlation
  • Tactical threat assessment
  • Defense gap analysis

AI Analysis Engine

DeepSeek API Integration (OpenAI-compatible):

  • Vulnerability classification
  • Impact analysis
  • Exploitation reasoning
  • Remediation guidance
  • Enrichment-aware prompt context
  • Exploitation likelihood labeling
  • English-only output for analysis and reporting

Fallback Mode (fully offline):

  • Structured mock intelligence generation (not random)
  • Deterministic threat analysis
  • Zero-dependency operation

Historical Context Storage

SQLite persists the operational state required by the platform:

  • Processed article fingerprints for deduplication
  • Extracted CVE and IOC records
  • Threat analysis output
  • MITRE ATT&CK mappings
  • Historical context records
  • Correlation clusters for related campaigns

Reporting System

Multi-format Output:

Format Use Case
JSON Machine-readable, automation, SIEM import
Markdown SOC reports, documentation, archives
CSV Spreadsheet analysis, bulk export
STIX STIX-like structured feeds

Report Contents:

  • Executive summary (threat overview)
  • Top 10 threats
  • Severity breakdown
  • Top CVEs with CVSS scores
  • IOC inventory and findings
  • MITRE ATT&CK overview
  • Correlation summary and cluster details
  • Remediation guidance

Feed Sources (Production)

Real security intelligence sources only:

Source Type Frequency
The Hacker News RSS Real-time
Krebs on Security RSS Daily
CISA KEV JSON API Daily
Mock Threat Feed Synthetic Test mode only

Validation & Resilience:

  • Retry logic with exponential backoff
  • Request timeout enforcement (15s default)
  • Rate limiting compliance
  • Deduplication across sources
  • Input sanitization
